Brocade Virtual ADX Supported Features
1
Advanced networking with support for static and dynamic routing
The system supports both static and dynamic routing (for OSPF, BGP and RIP protocols) as well as
route health injection (RHI). This combination of features allows administrators to configure the
system so that an upstream router can pick the optimal route for reaching a virtual server.
High availability for active and standby deployments
To ensure undisrupted transaction processing the Brocade Virtual ADX can be deployed as an
active-standby pair. In this configuration two ADX devices can be configured so that one device is
set up to actively manage traffic while the other acts as a standby device and is positioned to take
over in the event of a failure. When a failover occurs the active device will transition control to the
standby device effectively switching the roles of the two devices. The result is a more robust load
balancing topology.
Rate Limiting
For added control the Brocade Virtual ADX now supports rate limiting at the port level allowing
administrators to define the maximum throughput for a given port. The system then monitors the
rate of traffic passing through that port and takes preventive action, in real time, based on the
predefined traffic rate.
Support for Brocade Virtual ADX as a GSLB site for increased
availability across datacenters
Global Server Load Balancing (GSLB) is a common deployment topology used to manage traffic
across one or more datacenters or sites. These sites are often distributed geographically. In this
release of the Brocade Virtual ADX, a Brocade GSLB controller can now recognize a Brocade Virtual
ADX instance as participating in a GSLB site, further increasing availability of the entire application.
Extended hypervisor support for heterogeneous environments
The Brocade Virtual ADX can now be deployed on a variety of third party hypervisors including
VMware ESX, Citrix XenServer and KVM. Supported releases are listed below:
• VMware Hypervisor ESX version 4.0 or later and VMware vSphere Client version 4.0 or later
• KVM host 0.9.0 or higher
• Citrix XenServer hypervisor version 6.2.0 or later and Citrix XenCenter client version 6.2 or later
